IMPROVEMENTS IN GHANNELLIN'G MACHINES.

, To 'ALL wHoM 1T MAY CONGERN:

Be it known that I, HENnY S. VRQOMAN, of the city of Hoboken, county'oiv Hudson, State of' New` Jersey, have invented certain new and useful improvements in Channelling Machines and I do hereby declare that the following, taken in connection with the drawings which accompany and form par'. of this specication, is adescription of my invention sucient to enable those skilled in the art toy practise it.

The invention relates to the details of construction of machines for channelling. boot and shoe-soles, and to that class of machines generally known as the McKay Channellers. The inven4 ion consists in sorapplying the arm which carries the knife and groover and the presser-wheel that it' may be :'emoved from the machine without withdrawing the pin upon which it springs; in so applying this arm that i't may hey moved longitudinally' to adjust the position of the knife and groover 'laterally with relation to the edge gnidefwheel; in applying the knife and groover to a block so fastened to the arm as to be capable of vertical movement toadjust the depth of cut of the channel; in a provision for adjustment of the groover vertically independently from and' relatively to the knife; in the employment of a gauge or setting-plate to determine the position of'thekniferwhen replaced after removal from the machine; in slotting out through the edge of the plate thel screwholes of the knife-stock. to' permit removal of thelknifewithout withdrawing the screws; in combining with the rod' by :which the arm is. connected to the base-plate and the spring which holds the arm in position a lifter-lever for raising the arm to enter the sole; and in the manner of applying this rod to the arm. The drawingsl represent a 'channeller embodying my improvements.

In its general organization with reference to cutting the chahnel the machine does not' di'er' essentially from the channeller above referred to, the changes and modifications introduced by me being: principally' for the purpose of rendering the parts more readily adjustable, this general organization being as follows.r

A denotes the bed, which, nvith its standards or housings, B B, makes up the frame-work of the machine, supporting the shaft F, which carries the feed-wheel G; this shaft being driven by the crank I, through-gearings D E, and carrying the gear` H, meshing into and driving the gear I, fixed on shaft J, which carries the presser-I wheel If; this shaft J, turning in bearings in an arm L, which swings vertically on the journal-pin a, fixed in top 0f the rear standard B. The inner side of wheel G carries the bevel-gear p, meshing into thc` tccth= of thex bevel-pinion T, turning on the pin w, the periphery of the upper portion forming the guide against which theedgc of the sole is held as it passes between the feed and presser-wheels G K to the action of the knife and groovei which cut the channel. This being the general and well-understood construction, my improvements will be now described.

The channelling tool being connected entirely with the arm L, and it being often desirable to inspect thesetools Without removing them from position with respect to the arm, a means for ready removal of this arm from 'the machine is desirable, and for this purpose I slot out the bearing b to the outer side of the arm, so that when the front end of the arm is disconnected from the bed A the arm may be slipped from the journal-pin a, or upon the same, whenever desirable so to do, without removing the journal-pin. To still furthe: facilitate the removal of the arm L, it is connected to the rod U (to be presently described) by a sliding-pin, q, extending; through the rod and transversely through the arm, the length of its bearings in the arm rendering the employment of a screw and nut to keep it in position unnecessary. The construction of the slot b also gives to the arm a capability of longitudinal movement to carry the cutters to a greater orless distance from the edge of the sole, which longitudinal movement is effected as follows: `a sliding-block, M, placed upon shaft J, rests upon a pin, d, projecting from standard B, the block being slotted where it rests upon this pin, as seen at c, this slot permitting vertical movement of the block with the shaft, and longitudinal movement of the shaft and arm together, with respect to the block. An adjusting screw, C, passes through this block, the screw upon its end Workingin to a female screw formed in the arm L. By turning this screw (which is kept from endwise movesoso? ment by its head and a collar, d', fastened vupon it) the arm L, and with it thc prcsscnwheel and cutters, will be moved from or towards `the edge-wheel T, permitting the distance from the edge of the sole at which the channel shall b-e cut 'foibe determined by simply turning this adjustingr screw C, as will be understood from iig. 1. The rod, U, extends through a stud, V, from the standard B, and has at its lower end a screw, upon which a. nut, y, works. rounl the rod, between the nut y and stu'd V, is a stout spiral spring, X, (bearing against washers r s,) the stress of the spring holding the arm L down and through the presser-wheel, keeping the sole pressed iirmly enough between the feed-wheel G and wheel K, to insure its progression to the action 'of the cutters.

The pressure is increased or diminished by turning the nut y. Sometimes, however, it is necessary to reduce or remove this pressure while the machine is in operation or to enter the sole, and for this purpose I Ivapply a lever, W, to the. plate A and rod U, as follows :V the rod extends loosely through one end of this lever, and between this and its opposite end it turns on a fulcrum-pin supported in a bearing resting upon or projecting from theplate A.- The outer end of thislever may carry a hook, to which a pedal strap maybe fastened,

.to be operated by the foot of the operator. By depressing the outer end of the lever the inner end is pressed 'up against the nut y, and lifts the rod, arm, presser-wheel, and cutters, as will be readily understood.

It is often desirable to vertically move the knife and groover together, with reference to the presser-wheel, to vary the depth of channel Without disturbing the relative position of the cutters.A For this'purpose I attach both cutters to a movable block, N, (or to an auxiliary cutter-block, O, xed to and projecting from this block N,) instead of fastening them to the head of the arm L; this block N (which is preferably `made hollow) being secured to the arm L by a screw bolt g, and held in position by such bolt anda stout spring, f, the extent of projection of thevcutters below the horizont-al planey of the lower surface of the presser-wheel, or below the lower surface of thc gauge v, and the corresponding depth of cut, being regulated and determined by the adjusting screw g, as will be understood from gs. 1 and 3. In applying the knife-stock to the machine, the inclination ot' the blade is first adjusted by hand and by trial, until it cuts-the slit as may be desired. In order that the knife may be reset after removal to the same inclination without the inconvenience of adjusting it in position by trial, I apply a gauge-plate, P,Yas seen in iig. 5; this plate being fastened to the side of the block by an adjusting screw, z'. Now, having set the knife-stock Q in such mannervas to bring the blade to its proper inclination, and having fastened the stock in position by the screw 7L, I set the plate P so that its adjacent sides rest against the sides of the stock Q, and fasten it there by the screw i. This being done, it will be evident that whenever the knife-stock Q has been removed,`it may-bc replaced so as to bring the blade in the exact position it previously occupied, by setting its sides against the edges of the plate P, and there fastening it by its screw, 7i. Through the top of the casting N passes a bolt, k, which has a screw-thread eut on'its lower extremity, and fltsinto a female screw in the upper end of the vertical rod Z, which carries at its lower end a groover-block, R, (tig. 4,) which is kept from turning horizontally by means of the guide rods m. (See fig. 5.) The groover-block is bored through horizontally for the reception of a circular rod or pin, n, projecting out from the face of the metal plate S, (iig. The other end of the rod 71, is provided with a screw-thread, on which turns the screwnut o. The stock of the groover is 'slotted out at the upper end, which fits snugly against the under surface of the projecting part of the groover-block R, and when the groover is to be set, its stock is slipped between the block R and the plate S, and the yscrew-nut o is then turned so as to clamp it firmly in place. A screw, j, yprojects up from the top of the knife-block O, seas to prevent it from being brought into the path of the parts which control the adjustments of the groover tool. (See figs. 3 and 5.) The holes in the knife-stock Q, through which pass the screws z, 7L, are slotted out (see iig. 5) to the edge of the stock, so as to allow of the removal of the knife without the'necessity of withdrawing the screws, as has heretofore been done.

From this description it will be seen that all the adjustments necessary in working these machines are provided for in such manner that the operator may produce whatever changes may be necessary in reference to channelling without the aid of a skilled mechanician. Much difficulty has been heretofore experienced in working this class of machines, but with the changes and modifications introduced by me these diiiculties have been mostly overcome.

l. I claim so applying the arm L to the machine that it may be removed from the frame or standards without withdrawing the pin a upon which it swings.

2. Also, the provision for longitudinal movement of the arm to adjust the cutters with reference to the edge guidewheel, substantially as set forth.

3. Also, in combination with the arm L the block N, (or the auxiliary block 0,) carrying the cutters, and made capable of vertical adjustment to simultaneously 'regulate the depth of cut of the knife and groover, substantially as described.

4. Also, the slotted construction ofthe knife-stock Q, (in combination with a groover-stock and other parts of a channelling machine,) to permit its removal without withdrawing the screw L, substantially as set forth 5. Also, in' combination with the stock Q the gauge-plate P, for determining the position of the knife when replaced, substantially as described. Y' HENRY S. VROOMANV.,v
